At JDMC Constructions, our aim is to make the process as straightforward as possible from day one.

Choosing a licensed builder means your project is completed safely, legally, and to the highest standard. Licensed builders are qualified, experienced, insured, and accountable. This means your project meets all Australian regulations, gives you legal protection and peace of mind throughout your build.

Yes, JDMC Constructions is a fully licensed and insured builder registered with the Building and Plumbing Commission (formerly the Victorian Building Authority).

Registration Number: CDB-U 71192

Possibly. It’s always best to start by checking with your local shire council. As the Building and Plumbing Commission (formerly the Victorian Building Authority) regulates Victoria’s building and plumbing industries, its also a good idea get advice from them too.

The type of permit depends on what you’re planning to do.

• Building Permit – Needed for most structural work, including extensions, renovations that alter walls or framing, or anything affecting plumbing and drainage.

• Planning Permit – Required if your project changes the external appearance of your home, sits close to boundaries, or is in a heritage or special zoning area.

• Cosmetic Work – Simple updates like painting, new flooring, or replacing cabinetry usually don’t need a permit.

At JDMC Constructions, our service extends to assisting you through the permit process as well as working with your building surveyor and/or council to make sure everything’s in place before construction starts.

You may need none, one or all of this documentation. What you require will depend on your project.

-Plans -Plans are graphical representations of what a building will look like once built.  They consist of a site plan, floor plan, elevation plans and landscaping plans.  

-Engineering Drawings -These are a set of plans that detail how a building or structure will be built. They include multiple views of a component of a build.

-Soil test -This tests the soil on a property to gather information about the soil type.  It is used to determine and design of any footings and foundations to be used.

-BAL rating report -This is a Bushfire Attack Level Report which outlines the specific level of risk to properties that are prone to bushfires.  It rates the intensity of a location's potential exposure to bushfire.

-LCA -This is a Life Cycle Assessment which provides information to understand the energy usage and other environmental effects that are associated with the entire life cycle of a building.  It evaluates the impact of a product, a system or an activity on the environment.

Absolutely. We can coordinate with your building surveyor, local council, engineer, architect, draftsman and any other professional to make sure all required documents and approvals are handled properly.

We have the knowledge and expertise to help guide you to make the process as smooth and stress-free as possible.

This decision is a decision only you can make, and we recommend you research the two areas as there are significant differences between an architect and a draftsman. 

Architect’s have considerably higher education, training and experience.  They also have a licence to practice architecture.  Architects have more responsibility and can undertake more complex designs. 

Draftsman provide drawings for construction projects and create clear and concise drawings for builders to follow. 

Yes, absolutely. We regularly collaborate with architects, draftspeople, and interior designers.
